8 Claims. 31. 533) My invention relates to tops for percolators and more particularly to a combined lock and protector adapted for use with percolator tops.

In the usual construction of percolators, the

a cover is provided with a glass dome or top destrikes some other object such as a cup and breaks it. Another difiiculty encountered in the use of conventional mountings for the tops is that the hot liquid is free to contact directly with the glass and the resultant expansion causes the top to crack.

My invention is designed to overcome the deficiencies of the prior art arrangements and consists essentially of a combined protector for the glass and locking means for holding the top securely in position in the cover. The protector portion of the device comprises an enclosed member positioned within the glass top directly over the riser tube, and constructed and arranged to prevent hot liquid from contacting with any portion of the glass. Locking means are associated with the protector by means of which it is held in the operative position and the glass top is securely locked to the percolator cover.

An object of my invention is to provide an improved lock and protector for percolator tops.

Another object of my invention is to provide a protector for percolator tops wherein liquid is prevented from contacting with the top.

Still another object of my invention is to provide a protector arrangement for percolator tops whereby forced percolation is effected; thus preventing the coffeefrom boiling over;

A still further object of my invention is to provide a fastening device'for percolator tops by means of which a top can be easily removed and replaced.

With these and other objects in view, which may be incident to my improvements, the invention consists in the parts and combinations to be hereinafter set forth and claimed, with the understanding that the several necessary elements, comprising my invention, may be varied in construction, proportions and arrangement, without departing from the spirit and scope of the appended claims.

In order to make my invention more clearly understood, I have shown in the accompanying drawing means for carrying the same into prac*- tical effect, without limiting the improvements in their useful applications to the particular constructions, which for the purpose of explanation, have been made the subject of illustration.

In the drawing:

Fig. 3 is a detail view of the fastening means.

Fig. 5 is a plan view of the inside of the top shown in Fig. 4. I r

Fig. 6 is a detail view of the locking means used with the protector showing Figure 4; and

Fig. 7 is a detail view of this locking means showing the interior surface thereof. I

Referring to the drawing and more particularly to Figures 1 and 2, there is shown an upper portion .of the body 1 of a percolator having a cover 2,- with glass top or dome 3 mounted therein. The cover member 2 is of conventional construction, hinged to the percolator body 1 and provided with a downwardly extending flanged portion 4, defining an opening in the cover to r'eceivethe top 3'. The inner periphery of the opening is recessed as at 5 to accommodate projections formed onthe' glass top.

The top is also of conventional type, having an upper portion 6, forming a hand gripby means of which the percolator cover may be opened or closed, a. peripheral bead '7 and a skirt-portion 8 having lugs or projections 9 formed thereon. In the present arrangement the top is furtherv provided with recesses 10 at diametrically opposite points on the skirt portion, said recesses being adapted to receive fastening elements to hold the top securely to the" cover, as will be explained in detail hereinafter. g

The improved percolator top protector and locking device comprise a cylindrical body por-' 'tion 11 having a conical shaped closed end 12.

It will be notedthat the apex 13, of the closed end of the protector, is expanded slightly so that it extends above the normal lateral surface of the conical portion. The purpose of this construction is to direct the flow of coffee or other liquid in the desired direction away from the deflector with minimum splashing'incidental to the abrupt change in direction of flow of the liquid.

ATENT OFFICE" '11 are two support arms 15 formed with lock members or hooks 16 at the ends thereof. Each hook comprises a downwardly extending portion :17, a horizontal piece 18, and an upwardly inclined portion 19 terminating in a bent over end 20 adapted to seat in one of the recesses 10.

In applying my improved protector andpera colator top fastening device to-a cover; the glass is inserted in the openingformed in the cover, with lugs 9 registering with the recesses 5 and bead '7 resting upon the flanged portion 4 of the:

cover. The top is thereafter turned so that the lugs 9 move out of the recesses and'contactwith the inner periphery of the opening to hold the top in the seated position. The protector is then inserted in the top, with the closed end 13- di-. iiectly over the riser tube 2 1, after which the ends 20 0f the hook members are inserted into the recesses l0 -formed in the skirt portion. 1

The glass top is thus securely locked to the cover and may be subjected to severe handling without any possibility of'its becoming loose or dropping out. In this connection it will be noted that the bent over portion of thehook contacts with the edge of the flanged'portion 4 and that therecesseslO, which slope inwardly, together with the'hook ends, provide a' wedging action which serves to draw the, top down tightly into the seven-Although use may be made of the lugs 9*to' efiect a preliminary looking, it will be understood thatwith my improved locking arrangement that the lugs can be eliminated and the protector can be applied to a cover, and se-' cure'ly lock the top-to the same without moving the lugs out'of register with recesses 5.

' For the purpose of preventing the deflector from rocking about its" points of contact with the skirt 8," the horizontal portions 18 are provided with extn'sions' 22 whereby movement of the protector with respect to the top is prevented. It isimportant that the apex 13of the-protector always remain directly over'the riser tube'for the reason that the design of the protector is such that the hot liquid -or coffee first strikes the conical portion and is-dire'cted away from the'top in a man-- ner to prevent excessive agitation of theliquid.

"Referring to Fig. 3, which is a detailed view of one of the fastening elements,- it will beseen that the "hook end 20 is bent over so that it will easily slide into one of the recesses 10 and at the same time contact with the flanged portion 4 thus 605 arranged to give a spring action 'so that when the drawing'the'glass down into tight engagement with the; sides of the flanged portion forming the opening in the cover. The hook members are ends 20 coincide with the recesses they will slide under-the flanged portion 4 and seat in said recesses.

, Referring to Figs. 4 and 5, I have shown a modification of thearrangement disclosed in Figure 1 wherein the fastening elements are adaptedto engage with lugs or projections 23 formed onfthe skirt portion of the glass top. .In this. arrangement the protector device is the same asv that shown in Figure 1, however, the hook members are provided with openings 24 adaptedto fit over the lugs 23-and hold the protector in the locked position on the top. It will be noted that theends 25;,ofgzthe fastening elements are bent outwardly '26 engages with the projection and due to the con-figuration of this portion, movement of the hook away from the projection is prevented. It

"will 'befurther noted that the curvature of the end of the hook 25 is such as to permit the flanged portion 4 to seat between the end portions and theskir-t of flanged portion 4 to seat between the end portions and the skirt of the top whereby a tight engagement is eifected between the parts.

It will nowbeappreciated that I have provided an; improved protector device for the tops of percolators which is of general application to percolators and adapted" to prevent 'the hot coffee or other liquid from contacting with any portion ofthe glass.- The concave-.design 'of the protector ca uses-=thewater to be forced downwardly over the cofieergroun'ds and the resultant forced percolation destroys the air or gas bubbles inthe liquid thereby preventing the coffee fromboiling over.

While Ihave shown and described the'preferre'd embodiment of my invention, I wish it to-be 'understood that I do not confinemyself tothe' pres cise' details of construction'herein set forth, by way of illustrationsyas it is apparent thatma'ny changes and variations may be made therein, :by those skilled in the'art, without departing from the spirit of the invention, or exceeding the scope of the appended claims;
